This guide will walk you through the process of setting up a new validator on Liberland Chain.
Note:
DO NOT expose your validators RPC ports (9933 and 9944 by default) publicly on the internet. Treat validators with more care than full nodes.
You do not need to a run a validator to earn LLD staking rewards. As a user you can simply become a nominator and stake your coins without needing to run a validator.
~30 GB of free disk space
4GB of RAM, but swap is ok, see if you have less than 4GB of RAM
Liberland wallet with at least 200 LLD.
If self hosting is not practical, the up-to-date current order of recommended virtual server providers are
In search, type lightsail
Under Instances, click Create instance
Select Linux/Unix, OS Only, Ubuntu 22.04 LTS, scroll down and select the plan with at least 4 GB RAM, 1 vCPU and 60gb SSD
Scroll down and click on "Create instance"
Wait for a few minutes for a server to initialize
Click on the console icon on your instance to open a in-browser console
Follow the installation steps of this guide
This script is for Ubuntu and Debian servers. If you're not running Ubuntu or Debian, please contact dev team - they can add support for your distribution.
Run the following command on your server:
The script will ask you for confirmation before every action. It will:
install dependencies
download Liberland node
setup a systemd service, so that the node starts automatically
configure time synchronization
generate session keys for use in next step
The script gives the node time to start up, if it takes too long it will exit. If that happens, just wait a minute and run the script again.
If everything goes OK, you will see something like this:
Copy the session keys, you will need them when adding validator.
Monitor logs of your node.
While syncing, you will see Syncing
messages and lots of maybe_release ran all the way
messages.
When synced, maybe_release ran all the way
will mostly disappear and you will see mostly Idle
and Imported
messages.
This process will take a few seconds for every day the blockchain has been running - so expect a few hours.
Note that in order to do this step you will need some LLD, so ask someone to give you some if you dont already have it.
Visit Staking in Liberland dAPP:
Click "Switch to validator" button.
Set your commission (20 is fine) and session keys you got from installation step to Keys from rotateKeys
form.
Click "Start validator" button and sign the transaction.
Optionally, click on add stake and stake some LLDs
Immediately after adding validator, you should see it as "Waiting":
Now you have to wait to see if it gets elected to current set of validators. You may need to wait until new era starts and then the chance of being elected is based on the amount of staked LLD. To see current set of validators:
Visit Staking Accounts on Polkadot.js Apps:
Click "All validators" button.
Click "Active" button.
You should see list of active validators in the "Validators" table.
You will need your LLD, LLM, and an onchain citizenship to proceed. Follow the steps to proceed.
At the end of this process, you should have a wallet, and a funded citizen account on the mainnet. Log into with your liberland account to verify everything works so far.
and create an account.
If something went wrong and you need to get session keys manually, see .

Once your validator is up and running and you have a solid track record of no downtime you can ask other LLD holders to nominate your validator node.
